- Node of Ranvier
Axon part that is a gap in the myelin where voltage-gated sodium channels cluster and saltatory conduction takes place
In neuroscience and anatomy, nodes of Ranvier, also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space. Nodes of Ranvier are uninsulated and highly enriched in ion channels, allowing them to participate in the exchange of ions required to regenerate the action potential. Nerve conduction in myelinated axons is referred to as saltator... Wikipedia
